THOMAS J. SOUTHARD, OF RICHMOND, MAINE.

PUMP.

Specification of Letters Patent No. 32,724, dated July 2, 1861.

To all whom 'it may concern:

Be it known that I, THOMAS J. SoUTr-IARD, of Richmond, in the county ofSagadahoc, State of Maine, have invented cert-ain new and usefulImprovements in Pumps; and I do hereby declare that the same aredescribed and represented in the following specification andaccompanying drawings.

The nature of my invention and improvements in pumps consists in theapplication and use of a weighted fly wheel and a weighted lever orpendulum, operated by a crank in such a way and manner, that the weightof the pendulum acts to preserve the momentum from the applied power,when the pump is operated. y

To enable others skilled in the art to make and use the improvements inpumps which I have invented I will proceed to describe theirconstruction and operation referring to the accompanying` drawings inwhich the same letters indicate like parts in each of the figures.

Figure 1, is a plan or top view of two ship pumps with my improvements.Fig. 2, is an end elevation of the same.

A, represents a portion of the deck of a vessel with two pumps B, B,inserted through, and projecting above it.

O, is a rectangular frame arranged above the pumps and supported by fouror more posts D, D, shown in the drawing Fig. 2. The frame C, has twobars EF across it to which the stands F, F, are fastened to support therock shaft G, which is filled to turn freely in them for the purpose ofoperating the working beam IFI, which is fastened on it to traverse thepiston rods I, I, of the pumps B, B, which rods are connected to thebeam I-I, by the pins J, J, shown in Fig. 2.

To work the rock shaft G, and operate the beam and pumps the pendulumlever K, is fastened to it, which lever has a long slot L, in it for thecrank pin M, to traverse in which operates the pendulum level' K. Thecrank pin M, is fastened in the disk N, on the shaft I), which shaftturns in the stand F, and in the box Qt, on the frame O, shown inFig. 1. The fly wheel R, is fastened to the shaft I), and has a weightS, fastened in such a position in relation to the crank pin M, that theweight will be descending, while the crank pin is moving' the pendulumlever and weight T, out toward U, and thus aid the operator in workingthe pumps. The crank V, is fastened to the shaft I), in such a position,that when the operator is exerting his strength at the greatestdisadvantage the weight S, on the pendulum will be descending; and whenhe is exerting his strength to the greatest advantage the weight S, willbe ascending. The weight S, is fastened to the end of the pendulum leverK, and has an eye or staple in its lower side in which the rope IV, isfastened, so that the pumps may be worked by pulling the rope.

I have described and represented the crank shaft right under the rockshaft, and the crank pin working in a slot in the pendulum. But Icontemplate that the crank shaft may be put in some other position andthe crank pin arranged to work in a slotted arm from the rock shaft,instead of the pen dulum, or that the crank pin may be connected to thependulum by a link instead of working in a slot in it.

I have described my improvements as being applied to two pumps in a shipbut they may be applied to one or more pumps for pumping ships or toraise water for other purposes.

I believe I have described and represented my improvements in pumps, soas to enable any person skilled in the art to make and use them.

I will now state what I desire to secure by Letters Patent, to wit:

The combination of the weighted fly wheel; the slotted pendulum; crankpin M, and lever H, operating two or more pumps, when arrangedsubstantially as set forth.

In testimony that the foregoing is a proper description of myimprovements in pumps I have hereunto signed my name.

T. J. SOUTHARD.
